Google's Universal Cart lets AI spend your money across multiple retailers
Your AI assistant will now buy toilet paper for you automatically.
At Google I/O 2026, the company introduced Universal Cart, a new AI-driven shopping feature built atop the Universal Commerce Protocol (UCP). This open standard, co-developed with major retailers including Target, Shopify, Wayfair, and Etsy, allows shoppers to add products from multiple stores into a single cart and check out via Google Pay. The real power comes from Gemini's agentic AI, which runs in the background to analyze selections from across Google's ecosystem — YouTube, Gmail, Gemini, and Search — and then makes suggestions, checks compatibility, applies discounts, and even predicts future needs.
In live demos, the AI caught incompatibilities like a CPU and motherboard pair that wouldn't work together, and prompted users to switch credit cards to take advantage of a discount. More aggressively, Google aims to automate routine purchases: if you buy the same toilet paper every month, Gemini will add it to your cart and complete the purchase without your input. During a previous demo of Chrome's Auto Browse, Gemini could analyze a photo of party decorations, identify the items, and add them to the cart from various sites.
Google calls this 'digital laundry' — handling repetitive tasks so users don't have to. The company's VP of Ads and Commerce, Vidhya Srinivasan, said the goal is to make shopping 'more fun' by removing barriers between 'Add to cart' and 'Checkout.' However, the AI also tracks behavior and predicts purchases, raising privacy concerns. While Universal Cart is optional, its convenience is designed to increase conversion rates for retailers and lock users deeper into Google's commerce ecosystem.
- Universal Cart consolidates products from multiple retailers like Target, Shopify, Wayfair, and Etsy into one checkout via Google Pay.
- Gemini's agentic AI checks compatibility (e.g., CPU and motherboard), suggests better credit cards, and finds better deals in real time.
- The system can auto-purchase routine items (like toilet paper) without user interaction, and predicts future purchases based on behavior.
Why It Matters
AI agents automating purchases could greatly reduce shopping friction but raise questions about privacy and consumer control.
